Description

[0002] With the development of science and technology and the improvement of living standards, washer-dryers have become increasingly popular among consumers due to their outstanding advantages such as taking up less space, multi-purpose use and low price.

[0003] After users use a washing and drying machine to wash clothes, the water on the observation window and door seal will condense on the bottom of the inner wall of the door seal under the action of gravity. Since it remains moist for a long time, the door seal is prone to mold and bacteria, causing secondary contamination of clothes, which is not conducive to the cleanliness of clothes and human health, and seriously affects the user experience.

[0004] In the existing technology, a drain outlet is added at the connection between the bottom of the door seal and the outer cylinder to drain the accumulated water as much as possible, and antibacterial materials are used to make the door seal to minimize the growth of bacteria. However, since the area between the door seal and the observation window is still in a humid environment for a long time, the effect achieved by the above antibacterial measures is not ideal.

[0071] The clothes processing device may be a washing and drying machine, which can not only wash clothes but also dry clothes. As people's living standards improve, such clothes processing devices have long become one of the indispensable household appliances in daily life.

[0072] On the one hand, although the clothing processing device can provide drying air to the clothing processing barrel 1 through the drying component 2, and circulate the drying air in the clothing processing barrel 1 and the drying component 2 to dry the clothes in the clothing processing barrel 1, most of the drying air cannot reach the gap between the door seal 4 and the observation window 32, resulting in a large amount of residual liquid between the door seal 4 and the observation window 32. Although the prior art uses antibacterial materials to make the door seal 4 and adds a drain port at the bottom of the door seal 4 to drain the accumulated water that flows to the bottom of the door seal 4 under the action of gravity as much as possible, the area between the door seal 4 and the observation window will still be in a humid environment for a long time, and the door seal 4 cannot be effectively dried, and it will still be easy to mold and breed bacteria.

[0073] Example 1

[0074] Based on this, Figure 1-Figure 5 As shown, the laundry processing device according to an embodiment of the present invention includes: a laundry processing tub 1 having an air inlet 11, an air return port 12 and a laundry access port 13;

[0075] The drying component 2 is connected to the air inlet 11 and the air return port 12 respectively, and is used to provide circulated drying air for the clothes processing tub 1;

[0076] The sealed door 3 includes a door body 31 and an observation window 32. The door body 31 is openable and closable at the clothing access opening 13. The observation window 32 is connected to the door body 31 and moves with the door body 31.

[0077] The door seal 4 is arranged around the clothing access opening 13. When the door body 31 is closed at the clothing access opening 13, the door seal 4 is used to fill and seal the gap between the door body 31 and the clothing access opening 13;

[0078] Among them, the observation window 32 includes a protrusion 321 facing the interior of the clothing processing barrel 1 when the door body 31 is closed to the clothing storage and access port 13, and an air guide structure 5 is provided on the side of the protrusion 321 close to the air inlet 11. The air guide structure 5 is used to guide the drying air into the interior of the clothing processing barrel 1 and the inner ring of the door seal 4.

[0079] Specifically, the clothes processing barrel 1 can be a cylindrical barrel body, and the clothes processing barrel 1 is used to place various clothes to be processed. The clothes storage and access port 13 of the clothes processing barrel 1 can be a circular hole, which is used to place various clothes into the clothes processing barrel 1 or take them out from the clothes processing barrel 1. The air inlet 11 and the return air port 12 of the clothes processing barrel 1 are respectively connected to the drying component 2. The drying component 2 can heat the air and drive the air to circulate in the drying component 2 and the clothes processing barrel 1 to form a circulating dry air. The circulating dry air can dry the clothes in the clothes processing barrel 1, or dry the clothes processing barrel 1 and the door seal 4.

[0080] The sealed door 3 includes a door body 31 and an observation window 32. The shape of the door body 31 corresponds to the clothing storage and access opening 13. The door body 31 can be hingedly connected to the clothing treatment tub 1. By flipping the door body 31, the observation window 32 can be flipped together. The observation window 32 is made of a transparent material and is arranged on the door body 31. Objects in the clothing treatment tub 1 can be seen through the observation window 32. The flipped door body 31 and observation window 32 have two states: one is a closed state, in which the observation window 32 and the door body 31 block the clothing storage and access opening 13. In this state, the clothing in the clothing treatment tub 1 can be washed or dried, or the clothing treatment tub 1 and the door seal 4 can be dried. The other is an open state, in which the observation window 32 and the door body 31 are opened from the clothing storage and access opening 13. In this state, clothing can be placed in the clothing treatment tub 1 or removed from the clothing treatment tub 1.

[0081] The door seal 4 can be made of antibacterial material and a ring-shaped rubber with a certain elasticity. The shape of the door seal 4 is adapted to the clothing storage and access port 13, and is arranged around the clothing storage and access port 13. When the door body 31 is closed to the clothing storage and access port 13, that is, when the door body 31 and the observation window 32 are in a closed state, the door seal 4 contacts the door body 31 and the clothing storage and access port 13 respectively, and can seal the door body 31 and the clothing storage and access port 13 to ensure the sealing effect of the sealed door 3.

[0082] When the door body 31 is closed to the clothing access opening 13, that is, when the door body 31 and the observation window 32 are in the closed state, the observation window 32 has a raised portion 321 on the side facing the interior of the clothing treatment barrel 1. The raised portion 321 has a smooth transition arc around it. The raised portion 321 is provided with an air guide structure 5 on the side adjacent to the air inlet 11. The drying air entering the clothing treatment barrel 1 from the air inlet 11 first flows to the air guide structure 5. The air guide structure 5 can be a smooth inclined surface or arc surface structure to guide the drying air, which can guide the drying air that has just entered the clothing treatment barrel 1 from the air inlet 11. The drying air in the clothing treatment tub 1 enters the interior of the clothing treatment tub 1 and the door seal 4, so that a part of the drying air enters the clothing treatment tub 1 to dry the remaining accumulated water in the clothing treatment tub 1, and the other part of the drying air enters the gap between the door seal 4 and the observation window 32 to dry the door seal 4. It can not only dry the accumulated water at the bottom of the door seal 4, but also take away the moisture on the surface of the door seal 4 and the observation window 32, so that the door seal 4 can be in a dry environment, avoiding the door seal 4 from being damp and moldy and breeding bacteria, causing secondary pollution to the clothes, and seriously affecting the customer's usage experience.

[0083] The door seal is an annular member, and the inner ring of the door seal is the side where the inner wall of the door seal in the radial direction is located.

[0084] According to the clothing processing device of an embodiment of the present invention, an air guide structure 5 with a diverting function is provided on the inner raised portion 321 of the observation window 32. After the drying air generated by the heating of the drying component 2 enters the interior of the clothing processing barrel 1 from the air inlet 11 of the clothing processing barrel 1, the air guide structure 5 can not only guide the drying air to the internal space of the clothing processing barrel 1 to dry the inside of the clothing processing barrel 1, but also guide the drying air to the inner ring side where the door seal 4 is located, so that the drying air can flow in a ring shape along the gap between the observation window 32 and the door seal 4, and dry the water droplets remaining on the observation window 32 and the door seal 4, as well as the accumulated water gathered at the bottom of the inner wall of the door seal 4, and dry the door seal 4 to prevent the door seal 4 from being moldy and fungi due to being in a humid state for a long time, causing secondary contamination of clothes, and seriously affecting the user experience.

[0085] In some embodiments, the wind guide structure 5 includes a first wind guide surface 51 and a second wind guide surface 52;

[0086] The first wind guide surface 51 and the second wind guide surface 52 are respectively provided on the raised portion 321;

[0087] Wherein, the first air guide surface 51 is inclined from the side where the air inlet 11 is located toward the interior of the laundry treatment tub 1;

[0088] The second air guiding surface 52 is inclined from the side where the air inlet 11 is located to the side where the door seal 4 is located.

[0089] Specifically, the first air guide surface 51 can guide a part of the drying air close to the air inlet 11 to the side close to the inside of the clothing processing barrel 1, and the second air guide surface 52 can direct a part of the drying air close to the air inlet 11 to flow along the second air guide surface 52, and flow along the second air guide surface 52 to the side where the door seal 4 is located, so that this part of the drying air can flow in the annular gap between the door seal 4 and the observation window 32, dry the moisture between the door seal 4 and the observation window 32, and dry the door seal 4.

[0090] In some embodiments, the first air guiding surface 51 and the second air guiding surface 52 intersect to form a parting line b, and an extension line of the parting line b passes through the center of the air inlet 11 .

[0091] Specifically, the parting line b between the first air guide surface 51 and the second air guide surface 52 is the dividing line of the two air guide surfaces. After the parting line b is extended and passes through the center of the air inlet 11, the drying air discharged from the air inlet 11 can flow evenly to the first air guide surface 51 and the second air guide surface 52, thereby avoiding the first air guide surface 51 introducing too little drying air into the clothes processing barrel 1, affecting the drying inside the clothes processing barrel 1, and avoiding the second air guide surface 52 introducing too little drying air into the door seal, affecting the drying of the door seal.

[0092] In some embodiments, the first air guiding surface 51 and the second air guiding surface 52 are inclined surfaces or arc surfaces with the center located in the laundry processing tub 1 , respectively, at first and second preset angles relative to the air outlet direction of the air inlet 11 .

[0093] Specifically, the first preset angle can be any angle between 40° and 80°, the second preset angle can be any angle between 25° and 50°, the inclined surface can be an inclined surface with a smooth surface, the first air guide surface 51 is inclined toward the interior of the clothing processing barrel 1, and the second air guide surface 52 is inclined toward the side where the door seal 4 is located. The arc surface can also be an arc surface with a smooth surface with an arc length not exceeding 1 / 4 of the circumference. The first air guide surface 51 and the second air guide surface 52 can guide the drying air through the inclined surface or the arc surface, and can smoothly change the flow direction of the drying air, so that part of the drying air can enter the interior of the clothing processing barrel 1 for drying, and part of it can enter the gap between the door seal 4 and the observation window 32 for drying.

[0094] In some embodiments, the wind guide structure 5 includes a third wind guide surface 53 and a fourth wind guide surface 54;

[0095] The third air guide surface 53 is inclined from the side where the air inlet 11 is located toward the interior of the laundry processing tub 1;

[0096] The fourth air guiding surface 54 is located on the side of the third air guiding surface 53 , and the fourth air guiding surface 54 is inclined from the side where the air inlet 11 is located to the side where the door seal 4 is located.

[0097] Specifically, the air guide structure 5 may also include a third air guide surface 53 and a fourth air guide surface 54, through which the drying air is guided. The third air guide surface 53 can guide the drying air close to the air inlet 11 to the side close to the inside of the clothing processing barrel 1. The fourth air guide surface 54 is arranged on the third air guide surface 53. When the drying air reaches the surface of the third air guide surface 53, part of the drying air will flow along the fourth air guide surface 54 and flow to the side where the door seal 4 is located along the fourth air guide surface 54, so that this part of the drying air can flow in the annular gap between the door seal 4 and the observation window 32, thereby drying the moisture between the door seal 4 and the observation window 32 and drying the door seal 4.

[0098] In some embodiments, the number of the fourth wind guide surfaces 54 is two, and the two fourth wind guide surfaces 54 are respectively located on both sides of the third wind guide surface 53 along the first direction a;

[0099] The first direction a is perpendicular to the air outlet direction of the air inlet 11 .

[0100] Specifically, the air guide surfaces respectively arranged on both sides of the third air guide surface 53 along the first direction a can divide the drying air that can enter the gap between the door seal 4 and the observation window 32 into two streams, and dry the annular gap between the door seal 4 and the observation window 32 on both sides along the first direction a at the same time, which can effectively improve the drying efficiency.

[0101] In some embodiments, the two fourth air guiding surfaces 54 are symmetrically arranged in the air outlet direction of the air inlet 11 .

[0102] Specifically, the two fourth air guide surfaces 54 can be two identical inclined surfaces or curved surfaces, and are positioned relative to each other, so that the two streams of drying air entering the annular gap between the door seal 4 and the observation window 32 can be as even as possible, so that the drying force received by both sides of the gap between the door seal 4 and the observation window 32 along the first direction a is as similar as possible, avoiding the situation where the door seal 4 on one side is dry while the door seal 4 on the other side is still wet.

[0103] In some embodiments, the drying assembly 2 includes:

[0104] The drying air duct 21 is connected to the air inlet 11 and the air return port 12 respectively, and forms a circulation path of the drying airflow with the clothes processing tub 1;

[0105] A heater 22, which is provided on the drying air duct 21 and is used to provide drying heat for the drying air; and

[0106] The fan 23 is provided on the drying air duct 21 and is used to drive the drying air to circulate.

[0107] Specifically, the drying component 2 can heat the drying air and circulate the drying air between the drying air duct 21 and the clothing processing barrel 1, and can continuously provide drying air to the clothing processing barrel 1 and the door seal 4 to dry the clothing processing barrel 1 and the door seal 4.

[0108] In some embodiments, further comprising:

[0109] The first temperature sensor 6 is provided at the air inlet 11 and is used to detect the drying air temperature at the air inlet 11;

[0110] The second temperature sensor 7 is provided at the return air outlet 12 and is used to detect the drying air temperature at the return air outlet 12;

[0111] a third temperature sensor 8, provided in the laundry processing tub 1, for detecting the temperature of the drying air in the laundry processing tub 1; and

[0112] A gravity sensor is provided at the bottom of the laundry processing tub 1 and is used to detect the weight of the laundry processing tub 1;

[0113] The control module is used to control the drying component 2 according to the temperature signal or weight signal fed back by the first temperature sensor 6 , the second temperature sensor 7 , the third temperature sensor 8 and the gravity sensor.

[0114] Specifically, the first temperature sensor 6, the second temperature sensor 7, the third temperature sensor 8 and the gravity sensor are all electrically connected to the control module, and can transmit temperature signals or gravity signals to the control module, so that the control module can judge whether there are clothes in the clothing processing barrel 1 according to the weight of the clothing processing barrel 1, and control the operation mode of the drying component 2 according to the temperature of the drying air at the air inlet 11, the return air outlet 12 and the clothing processing barrel 1, so that the temperature of the drying air can be controlled to improve the drying efficiency of the drying air.

[0115] Example 2

[0116] As attached Figure 6 and attached Figure 7 As shown, an embodiment of the present application further provides a control method for a clothes processing device, wherein the clothes processing device is a clothes processing device according to any one of claims 1 to 7, and the control method includes:

[0117] Start the washing process to wash the clothes in the clothes processing tub 1;

[0118] After the washing process is completed, if the drying process is not performed, the door seal 4 drying process is started, and the drying air in the drying component 2 is guided to the inner ring of the door seal 4 through the air guide structure 5 to dry the door seal 4.

[0119] Specifically, after the clothes processing device performs the washing program and completes the washing operation of the clothes, a large amount of water will be accumulated in the clothes processing barrel 1. If the user runs the drying program for the clothes, there is no need to additionally start the door seal 4 drying program. The drying program will dry the clothes, the clothes processing barrel 1 and the door seal 4 at the same time.

[0120] If the drying process is not performed after the washing process is completed, the user's command input or the control module can automatically start the door seal 4 drying process, start the drying component 2, and guide the drying air to the inside of the clothing treatment barrel 1 and the door seal 4 through the air guide structure 5 to dry the clothing treatment barrel 1 and the door seal 4, so as to prevent the door seal 4 from being in a humid environment for a long time and becoming moldy and breeding bacteria, causing secondary pollution to the clothes and affecting the customer's usage experience.

[0121] In some embodiments, the door seal 4 drying process includes:

[0122] If the actual weight of the laundry processing tub 1 is greater than the empty tub weight of the laundry processing tub 1, wait for the laundry to be taken out;

[0123] If the actual weight of the laundry processing tub 1 is not greater than the empty tub weight of the laundry processing tub 1 , the drying component 2 is started to dry the door seal 4 .

[0124] Specifically, after starting the drying program of the door seal 4, the weight of the clothes processing tub 1 is first detected. By comparing the actual weight of the clothes processing tub 1 with the mass of the empty tub, it is determined whether there are any clothes in the clothes processing tub 1. If there are clothes, the door seal 4 will not be dried first, and the user will be asked to take out the clothes. If there are no clothes, the drying operation of the door seal 4 will be started.

[0125] In some embodiments, if the actual weight of the laundry treatment tub 1 is greater than the empty tub weight of the laundry treatment tub 1 , waiting for the laundry to be taken out includes:

[0126] The door 31 is unlocked, and the user is prompted to take out the clothes in the clothes processing tub 1 at the same time.

[0127] Specifically, when waiting for the user to take out the clothes, not only the door body 31 is automatically unlocked to enable the user to directly open the door body 31, but also a light is turned on on the display screen to remind the user to take out the clothes as soon as possible.

[0128] In some embodiments, starting the drying component 2 to dry the door seal 4 includes:

[0129] Heating the drying air to increase the temperature of the drying air and allowing the drying air to circulate in the clothes processing tub 1 and the drying assembly 2 for a preset time;

[0130] When the preset time is reached, the heating of the drying air is stopped, and the drying air continues to circulate in the clothes processing tub 1 and the drying assembly 2;

[0131] When the drying air is sufficiently cooled, stop the drying air circulation.

[0132] Specifically, when the drying component 2 is started and the door seal 4 is dried, the drying air can be heated by the heater 22 first to quickly increase the temperature of the drying air, and the drying air can be driven by the fan 23 so that the drying air can circulate in the clothing processing barrel 1 and the drying air duct 21. The preset time can be a pre-entered drying time. The preset time requires a period of time in which the drying air can dry the door seal 4 and will not continue to run and waste electricity. Preferably, the preset time can be 6 to 10 minutes.

[0133] After the preset drying time, the heater 22 is stopped, but the fan 23 is still running to allow the drying air to continue to circulate. At this time, the circulating air will gradually cool down. After the drying air is fully cooled, the drying air circulation is stopped to complete the drying operation of the door seal 4, which can prevent the user from opening the door too early and being burned by the hot air in the clothes processing barrel 1.

[0134] In some embodiments, heating the drying air, increasing the temperature of the drying air, and circulating the drying air in the clothes processing tub 1 and the drying assembly 2 for a preset time includes:

[0135] The temperature of the drying air is increased, and when the temperature of the drying air at the air inlet 11 is greater than a first preset value, the preset time is started.

[0136] Specifically, the drying air temperature at the air inlet 11 can be detected and obtained by the first temperature sensor 6. The first preset value is a pre-input temperature value. When the temperature in the clothes processing barrel 1 is higher than 65°C during the drying process, most of the bacteria in the barrel can be killed. At the same time, the evaporation of water in the barrel can be relatively saturated, thereby achieving sterilization, deodorization and rapid drying. Therefore, preferably, the first preset value can be set to 70°C, and the drying air temperature gradually increases. When the drying air temperature at the air inlet 11 is greater than the first preset value, the preset time is started again, which can ensure the sterilization and drying effect of the drying air.

[0137] In some embodiments, heating the drying air, increasing the temperature of the drying air, and circulating the drying air in the clothes processing tub 1 and the drying assembly 2 for a preset time includes:

[0138] The temperature of the drying air is increased. When the temperature of the drying air at the air inlet 11 is greater than a first preset value, the temperature of the drying air is adjusted so that the temperature of the drying air at the air inlet 11 is less than a second preset value and the temperature of the drying air at the return air outlet 12 is less than a third preset value, and then the preset time is started;

[0139] The second preset value and the third preset value are both greater than the first preset value.

[0140] Specifically, the drying air temperature at the return air outlet 12 can be detected and obtained by the second temperature sensor 7. The temperature can be quickly increased by increasing the power of the heater 22. When the drying air temperature at the air inlet 11 is greater than the first preset value, the drying air temperature is further controlled to make the drying air temperature at the air inlet 11 less than the second preset value, and the drying air temperature at the return air outlet 12 less than the third preset value. After the temperature is completed, the preset time is started again to avoid the drying air temperature being too high, so that the drying process is more stable and efficient, and the barrel is sterilized at the same time.

[0141] Preferably, the second preset value and the third preset value may be 68° C. and 80° C. respectively.

[0142] By heating quickly first and then controlling the temperature, the drying air can reach the desired temperature more quickly.

[0143] In some embodiments, the drying air is sufficiently cooled, including:

[0144] The temperature of the drying air at the air inlet 11 is lower than the fourth preset value, and the temperature of the drying air in the clothes processing tub 1 is lower than the fifth preset value.

[0145] Specifically, the fourth and fifth preset values ​​are both lower than the first preset value and can be temperatures at which a person feels slightly warm but not burnt. Specifically, the fourth and fifth preset values ​​can be 60°C and 50°C, respectively. The temperature of the drying air within the laundry processing tub 1 can be detected by the third temperature sensor 8. Drying is stopped only when the detected temperature of the drying air from the air outlet is lower than the fourth preset value and the temperature of the drying air within the laundry processing tub 1 is lower than the fifth preset value. Opening the door 31 is permitted, thereby preventing burns to the user.
